0.001 g and record its mass in Data Table 1. Find the mass of the key, together with its copper wire handle, to the nearest 0.001 g. Record the mass of this cathode assembly in Data Table 1. Without switching on the power supply, follow steps 2 through 5 of Part B to reassemble the circuit. To work out the actual number of electrons that leave the key while the plating occurs, you need to know two things: the current and the duration of the current flow. The current must be fixed at a steady value. Switch the power on, and simultaneously record the start time and immediately adjust the current to 0.25 A. Keep the current at a steady value for about 30 minutes, then switch off the power supply and record the finish time. Remove the key and copper anode. Rinse with distilled water and blot dry with a clean paper towel. Repeat steps 1 and 2 of Part C.

high- or a low-side injection will depend on the system design and whether the final demodulated signal needs to have the sidebands with an inverted frequency spectrum. In digital communications, this frequency inversion can be a major consideration, since the output of the IF is typically sent straight into a modem, which may or may not require inversion. But even if we do not have a choice as to whether we can frequency-invert or not, we may still select our high- or low-side injections throughout both the transmitter and receiver stages, and base our high/low preferences on the availability of oscillators, multipliers, or PLLs, as well as their cost and design complexity, along with the location of our undesired image frequency and the undesired mixer spurs.

As mentioned at the beginning of this part of the chapter, address translation devices are typically used to give you an almost inexhaustible number of addresses as well as to hide your internal network addressing scheme. Another advantage of address translation is that if you change ISPs or merge with another company, you can keep your current addressing scheme and make any necessary changes on your address translation device or devices, making your address management easier. Another big advantage that address translation provides is that it gives you tighter control over traffic entering and leaving your network. For example, if you are using private addresses internally, all traffic entering and leaving must pass through an address translation device. Because of this restriction, it is much easier to implement your security and business policies.

as measures because they are numeric fields, but key values are normally just automatically incrementing values, so making them measures doesn t make sense. Fortunately, any fields chosen as measures that shouldn t be there are easy enough to remove before continuing. The wizard also automatically adds a count to the measures for each fact table. By default, each fact table has its measures placed into its own Measure Group. A measure group is a collection of one or more measures, and by default each fact table has its own measure group. One exception is for measures that are distinct counts; for example, a store might have 10,000 shoppers during a week, but some people come in multiple times, so the number of unique shoppers might only be 7500. Distinct counts are put in a separate measure group by default for performance reasons. After selecting the measures the cube wizard next tries to detect hierarchies in the dimensions. As previously mentioned, this is an area in which the wizard often has problems. The good news is that the warehouse developer can modify the hierarchy design at this stage or after the wizard has completed. The wizard not only tries to determine hierarchies, but determines attributes as well. Attributes are those items that help describe a dimension item. For example, a hierarchy for a customer might be Country, State/Province, City, and finally Customer. However, a significant amount of additional information might be stored for a customer, such as age, height, weight, income level, education level, and more. A hierarchy that goes from Country to State/Province to Height probably doesn t make sense, and neither would going from Education Level to Weight. Therefore, many of these attributes are not part of a hierarchy but are still valid for analysis. The good news is that with these attributes, end users have the flexibility to analyze by nearly anything by simply selecting the attribute when constructing a query. The bad news is that users can be quickly overwhelmed when presented with a list of dozens of attributes from which to choose. This gets back to the discussion in 1; know the users. Most users would want to see just the hierarchies, because they provide a nice guided path through the data. Analysts would likely want to see everything and have complete flexibility to create their own queries, even if those queries involved many single attributes not included in any hierarchy. After completing the wizard, the cube is shown in a manner similar to that in Figure 3-10. Notice that the measures are shown along the left-hand side, broken into measure groups that match the fact tables. Also note that main window with the cube diagram is labeled Data Source View at the top. This is unfortunate and leads to much confusion among those new to Analysis Services. This is not the same as the data source view itself, but is just a representation of the tables from the DSV.

MATH NOTE Always be sure to check your work. You can differentiate the answer in the last example to recover the integrand, confirming that the integration has been performed correctly. EXAMPLE

As you can see, this program looks different from the average C program. To begin, notice that the header <iostream> is included, not <stdio.h>. The <iostream> header is defined by C++ and supports the C++ I/O operations. Notice one other thing: there is no .h extension to the name <iostream>. The reason is that <iostream> is a modern, C++-style header, which does not use the .h extension. The next line is

It is convenient to think of such a cone as the surface obtained by rotating the graph of f ( x) = x/2, 0 x 8, about the x-axis (Figure 8.34). According to our definition, the surface area of the cone is

Once you ve created your tunnel group, to associate VPN-specific attributes to it, use the following command:
